Install the sub power supply separately near the ventilator and turn it off when you clean the ventilator or you do not use the ventilator for a long period of time. Turn on the sub power supply which is installed separately. - The sub power supply is not supplied with the ventilator. Purchase the sub power supply individually. •If the circuit breaker (MCCB, ELB) is installed, the sub power supply does not need to be installed mandatorily. Install & Operation Ranges Install condition Outdoor air condition Indoor air condition 0~40°C, 80%RH below -15~40°C, 80%RH below 0~40°C, 80%RH below •If the ventilator is operated under the condition other than are indicated, it may not operate due to the protective device in the ventilator. Especially, if outside temperature is under -15°C, the ventilator does not operate at all. •Do not operate the ventilator when typhoon comes. Water may get in the room through the ventilator due to the rain and heavy winds. Maintaining your product Internal protections via the unit control system This internal protection operates if an internal fault occurs in the product. Type Description Against cold air The internal fan will be off to against cold air when the heat pump is heating. De-frost cycle The internal fan will be off to against cold air when the heat pump is heating. Anti-protection of internal battery The compressor will be off to protect internal battery when the product operates in Cool mode. Protect compressor The product does not start operating immediately to protect the compressor of the outdoor unit after it has been started. •If the heat pump is operating in Heat mode, De-ice cycle is actuated to remove frost from an outdoor unit that may have deposited at low temperatures. The internal fan is switched off automatically and restarted only after the de-ice cycle is completed. When the outdoor air suction temperature becomes lower than -10°C, the unit is changed to intermittent operation to prevent freezing of the heat exchanger element and dew condensation within the unit. 8 RHF050KHEA_IB,IM_E_32885-1.indd 8 2010-12-15 오전 11:26:47 Tips on using product Here are some tips that you would follow when using your product. ENGLISH TOPIC RECOMMENDATION Heat-EX Mode •Energy loss is minimized by recovering energy exhausted when indoor heating and cooling Quiet Mode •This allows you to have quiet sleep and fresh air while sleeping. •The ERV operation lamp will also be less bright. Outing Mode •This allows you to operate the ERV while you are away from home. •If the operational status is changed by another controller, the Outing mode is canceled. By-Pass Mode •The ventilation method is used when temperature gap of indoor and outdoor is not big. •Outdoor air flows into indoor. Auto Mode •The air is automatically changed depending on the degree of pollution in the indoor air. (Available only when the additional CO2 sensor is installed) Energy saving •Make operating condition for optimized energy saving. Clean up •Prevent the odor and dust of other places such as bathroom and kitchen from entering inside by making the supply air greater than the exhaustion air. (You can reverse this procedure to make the exhaustion air bigger than the supply air.) Cooling / Heating •You can have cooling and heating operation through the DX-COIL. •This unit should be used with air conditioners. Air conditioning is impossible only by this unit, because this unit does not have temperature control function. (It’s capacity is too small in order to control the room temperature to the whole) and should be operated in combination with standard indoor units. •When a remote controller is only connected to the ERV, independent operation is possible. However, temperature setting by remote controller is not possible. •In this ON/OFF operation by thermostat depends on factory setting. However, this value is changeable by installation/service mode on site. Frost & De-frost •When the product runs in Heat mode, due to temperature difference between the unit and the outside air, frost will form. If this happens: - The product stops heating. -The product will operate automatically in De-ice mode for 10 minutes. - The steam produced on the outdoor unit in De-ice mode is safe. No intervention is required; after about 10 minutes, the product operates again normally. The unit will not operate when it starts to de-ice. High indoor/outdoor temperatures •If both indoor and outdoor temperatures are high and the product is running in Heat mode, the outdoor unit’s fan and compressor may stop at times. This is normal; wait until the product turns on again. Power failure •If a power failure occurs during the operation of the product, the operating immediately stops and unit will be off. When power returns, the product will run automatically. Protection mechanism •After the compressor has stopped or the power supply has been switched on, the compressor will not run for 3 minutes for its protection therefore cool/warm air does not come out of the unit immediately. 9 RHF050KHEA_IB,IM_E_32885-1.indd 9 2010-12-15 오전 11:26:48 Checking the name of the parts Main parts Heat exchange element Exhaust Air OutdoorAir Return Air Supply Air Humidifier element(Option) DX-COIL Electrical component box Access panel Air filter(inside) 10 RHF050KHEA_IB,IM_E_32885-1.indd 10 2010-12-15 오전 11:26:48 Inspection hole ENGLISH A Access for inspection/ maintenance A Model 'A' (mm) RHF050KHEA 450 x 450 RHF100KHEA 550 x 550 There is access for inspection/maintenance for cleaning the air filter and the heat exchanger element.

If the unbalanced power is exceeded over 10% of supply rating, the indoor unit is protected, stopped and the error mode indicates. •To protect the product from water and possible shock, you should keep the power cable and the connection cord of the indoor and outdoor units in the iron pipe. •Connect the power cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must be incorporated in the fixed wiring(≥3mm). • You must keep the cable in a protection tube. • Keep distances of 50mm or more between power cable and communication cable. •Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must consider another power supplying method. •The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected from one breaker. • Use round pressure terminal for connections to the power terminal block. •For wiring, use the designated power cable and connect it firmly, then secure to prevent outside pressure being exerted on the terminal board. •Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible. • Over-tightening the terminal screws may break them. • See the table below for tightening torque for the terminal screws.

Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. 2. The address of the indoor unit is assigned by adjusting MAIN(SW01, SW02) and RMC(SW03, SW04) rotary switches. SW01 SW02 SW03 SW04 The designs and shape are subject to change according to the model. SW05 SW06 SW07 SW08 SW09 Setting Main Address The MAIN address is for communication between the indoor unit and the outdoor unit. Therefore, you must set it to operate the product properly. You can set the MAIN address from ‘00’ to ‘99’ by mixing SW01 and SW02. The MAIN address from ‘00’ to ‘99’ should differ from each other. Check the indoor unit address on the plan that you are to install and set the address according to the plan. •You may not need to set main address if you selected Auto Address Setting from the outdoor unit: see details on the outdoor unit installation manual. For Example When MAIN address is set as "12". Setting RMC Address The SW03, SW04 RMC switch is the address setting switch for controlling the indoor unit with the centralized controller. You must set the SW03,SW04 and K2 switch when using the centralized controller. You don't have to set the SW03 and SW04 RMC switch when not suing the centralized controller. For Example 42 When RMC address is set as "12".

It connects both sides of EXT1. - Only 1 unit can be connected. The picture displays the condition that external controller, kitchen hood and humid sensor are connected. If the external controller 1 is set to ON position, ventilator is operated in the last used condition. If you enter a kitchen hood, the supply air operates in Turbo fan speed and exhaust air operates in Low fan speed. When a signal comes to the humidification sensor, the ventilator (ERV) continues its operation. However, the humidity solenoid valve of the ventilator (ERV) will be closed and this will result in stopping the humidification operation.
